[ES] Se ha realizado durante 2009 una prospección de posibles vectores de los patógenos
causantes de amarilleos y deformaciones en apio y zanahoria observados en Villena
(Alicante) , centrandose en los hemípteros de las familias Cicadellidae y Aphididae y de
la superfamilia Psylloidea. Se han utilizado trampas adhesivas amarillas (para capturar
cicadelidos y psílidos) y muestreos de colonias en hojas (para los Afidos) en 4 campos
de apio y 3 de zanahoria.
La identificación de las capturas ha permitido elaborar una lista de especies de cada
grupo taxonómico (24 de cicadelidos, 3 de psílidos y 3 de afidos), entre las cuales destacan
por su frecuencia Asymmetrasca decedens (Paoli) y Empoasca solani (Curtis) en
el caso de los cicadelidos , Bactericera sp. y Cacopsylla pyri (Linnaeus) entre los
psílidos y Cavariella aegopodii (Scopoli) en afidos. En !as trampas adhesivas , el
7,55% eran cicadelidos y el 92,45% psílidos.
La evolución en el tiempo de las capturas indica que, en el caso de los cicadelidos,
presenta tres maximos en verano y dos mas en otoño. En el caso de los psílidos presenta
dos maximos en verano y dos mas en otoño. En Afidos, se establecen las colonias en
verano, sobre las hojas de estos cultivos herbaceos ya desarrollados.
Entre los cicadelidos de Ja tribu Empoascini, predominan las hembras en primavera,
igualandose los dos sexos en verano y predominando los machos en otoño.

[EN] During 2009, a survey of potential vectors of the pathogens that cause yellowing and
distortion on celery and carrot observed in Villena (Alicante) have been carried out. This
survey has been focused on Herniptera belonging to the families Cicadellidae and Aphididae
and Psylloidea superfarnily, and performed on four parcels of celery and three of carrot.
The leafhoppers and psyllids have been caprured using yellow sticky traps, and aphids
were sampled capturing colonies on leaves.
The identification of these potential vectors has allowed making a list of species in
each taxonomic group (24 Cicadellidae, 3 Psylloidea and 3 Aphididae). Leafhopper
species mostly found in Villena have been Asymmetrasca decedens (Paoli) and Empoasca
solani (Curtis). Bactericera sp. and Cacopsylla pyri (Linnaeus) have been identified as
the most abundant psyllid species, and Cavarieila aegopodii (Scopoli) has been the aphid
species primarily identified. In the yellow sticky traps, 7 ,55% were leafhoppers and
92,45% psyllids.
The evolution in time of the number of catches has indicated that the number of
leafhoppers have presented three peaks in summer and two more in the autumn. Specifically,
in the species of the tribe Empoascini , females has predominated in spring, males in
autumn and during the summer in both sexes the number have been equal. In the case of
the psyllids, there have been two peaks in summer and two more in the autumn. In aphids,
the colonies have been established on leaves of developed crops during the summer.
